CTS Thermal Clip System

In 1968, CMI developed and patented the "CTS" system that revolutionized the aluminum storefront framing industry. The unique CMI "thermal break" thermal clip design for a variable depth aluminum storefront framing system, with thermal performance comparable to curtainwall and structural performance surpassing that of standard storefront, unleashed versatile design flexibility at economical, storefront-value pricing that still remains a favorite today.
